BUTTON.

SPECIFICATION forming part of Letters Patent No. 255,727, dated March28, 1882..

' Application filed December 2'7, 1881. (No model.)

To all whom it may concern Be it known that I, WELLINGTON P. DOL- LOFF,of Providence, in the State of Rhode Island, have invented anImprovement in Buttons, of which the following is a specification.

My invention relates to that class of buttons where the shoe is made toturn to one sideot the post for insertion into the button-hole orremoval therefrom; and it consists in the pe- IO culiar construction ofthe post and the several parts contained'in the shoe, ashereinafterfully set forth.

Figure 1 represents an elevation of the button with the shoe turned toone side of the post, the hollow head ofthe button being shown insection. Fig. 2 represents a central section of Fig. 1, taken in theline to. Fig. 3 represents an elevation and central section of the post.Fig. 4 represents a plan and central 20 section of the spring. Fig. 5represents a plan and central section of the,,,piece for holding thejoint end of the post in itsproper position in the shoe.

In the drawings, Ais the head of the button;

B, the post; O,1the spring; D, the retaining or joint piece for thepost, and E the shoe-cap.

The postB may be either made of square wire or cutout of sheet metal ofsuitable thickness, the square or angular cross-bar 11, upon which thetongue 0 of the spring is made to act,

being offset to one side of the plane of the center of the post, asshown in Fig. 3, by which means thejoint of the post with the shoe maybe made to one side ofthe center of the shoe,

3 5 and yet secure a central position for the post when the shoe isturned toits locking position. (Shown by the dotted lines in Fig. 2.)

The spring 0 is cut out of sheet metal in the form of a partial circulardisk, as shown in Fig.

4, being cut away at one side, so as to form the tongue 0, which doesnot extend to the continnation of the circular boundary of thedisk.

The two splits a a extend for a short distance beyond the ends of theslots (1 d at each side 4 5 of the tongue 0, and serve to increase theflexibility ofthe tonguec ofthe spring without causing an opening to bemade in the spring other than necessary to receive the post, whichopening would tend to render the inner portion of the shoe unsightly,and the inner ends of the slots d (l serve as a stop to the post,preventing further movement when the shoe is turned to its lockingposition. I

The post-retaining piateD is provided with two lips, e andf, the outerlip, 6, being made considerably higherthantheinnor1ip,f. When theplate 1) and spring 0 are placed within the hollow ofthe shoe-cap E, andthe angular crossbar I) of the postis placed in the space between thelips e and f, the lip 0 will extend to about the plane of the outersurface of the spring, the inner lip,f, being made much lower, so as notto interfere with the proper action of the spring, but serving simply toretain the cross-bar Z) and prevent it from slippinginward toward thecenter of the shoe under thetongue of the spring. By this arrangement ofthe post, spring, and retaining-piece, whereby the joint is made at onesideot' the center of the shoe, a short post may be employed, which is adesirable feature in buttons of this class.

The spring-plate O is first cut out in the form of a circular disk,after which the slots d d are made from the edge of thedisk and theresulting spring-tongue c shortened, as above described. The plate soformed is then to be forming the splits a a and increasing thefiexibility of the spring-tongue 0 without removing the stock of theplate, which would form an undesirable opening to the inner portionofthe shoe.

In buttons of this class, where both ends of the spring-tongue areconfined by the rim of the shoe-cap, there can be but a very slightmovement in the spring except under great strain, causing arapid wear atthe angular corners of the cross-bar upon which the spring 0 is made toact, so that in a short time the shoe will be retained at any angularposition on the cross-bar in which it may be placed; whereas afterturning the corner it should automatically snap down to its looking orinserting p0 5 sitions; and in order to secure the desired lively actionof the shoe, I so construct the spring and connect it to the shoe-capthat one end of the spring-tongue will be free, thus securing a greaterrange of movement without injurious roe I 10 side of the center of thepost, retaining-plate D, provided with the lips e and made one longerthan the other, and spring 0, all arranged and op rating substantiallyas described.

2. In a button, the spring-plate 0, provided 15 with the spring-tonguec, shortened, as described, and acting at its end upon the pivotbar ofthe post, and having its flexibility increased by the shear-cut splits aa, made to extend beyond the slots 01 d at each side of 20 the tongue,substantially as and for the purpose specified.
